DiffThinker: Towards Generative Multimodal Reasoning with Diffusion Models

ICML 2026poster

While recent Multimodal Large Language Models (MLLMs) have attained significant strides in multimodal reasoning, their reasoning processes remain predominantly text-centric and fail to visualize and track intermediate visual states during the reasoning process, leading to suboptimal performance in c…

FrameThinker: Learning to Think with Long Videos via Multi-Turn Frame Spotlighting

ICLR 2026poster

While Large Vision-Language Models (LVLMs) have achieved substantial progress in video understanding, their application to long video reasoning is hindered by uniform frame sampling and static textual reasoning, which are inefficient and struggle to handle visually intensive video tasks. To overcom…

Spotlight on Token Perception for Multimodal Reinforcement Learning

ICLR 2026poster

While Reinforcement Learning with Verifiable Rewards (RLVR) has advanced the reasoning capabilities of Large Vision-Language Models (LVLMs), most existing methods in multimodal reasoning neglect the critical role of visual perception within the RLVR optimization process. In this paper, we undertake…

VideoSSR: Video Self-Supervised Reinforcement Learning

CVPR 2026

Reinforcement Learning with Verifiable Reward (RLVR) has substantially advanced the video understanding capabilities of Multimodal Large Language Models (MLLMs). However, the rapid progress of MLLMs is outpacing the complexity of existing video datasets, while the manual annotation of new, high-qual
